A long-simmering disagreement over the universe’s present-day expansion rate shows no signs of resolution, leaving experts ...

Ellipses are defined as curves that surround two focal points. At any point on the ellipse, the sum of the distance to both ...

A zero gravity bed is an adjustable bed base that allows you to elevate your head, shoulders and legs into a position that mimics the feeling of weightlessness. A NASA-approved sleep hack ...

With renewables booming and AI driving energy demand higher, gravity-based storage offers a geopolitically neutral solution that could stabilize power grids worldwide. As the global transition ...

Pretty much everything about the human body is a direct consequence of evolving over millions of years under the constant downward pull towards the Earth’s core. The effect of gravity on our ...

Developed in 1915, general relativity suggests that gravity arises because bodies with mass cause the fabric of spacetime (the four-dimensional unification of space and time) to warp. The greater ...

Einstein's theory of general relativity predicts gravitational memory, where space-time retains imprints from passing gravitational waves. Researchers are exploring if the cosmic microwave ...

Scientists are exploring a new way to test one of Einstein’s theories—an effect called gravitational wave memory, which could leave a permanent mark on space. The search for this hidden imprint has ...

March 8, 2025: Our weekly roundup of the latest science in the news, as well as a few fascinating articles to keep you entertained over the weekend.

So, where does the arrow of time come from? A growing group of physicists believe that it originates in the force of gravity itself. But to get there requires a radical reshaping of Einstein’s ...

and then by predicting a small cosmological constant (which explains how much and how fast the universe is expanding). The new theory also incorporates a G-field, or gravitational field.
